Country and river basin indicators are weighted averages of WRI's Aqueduct
Water Risk Atlas
indicator scores. Water Risk Atlas indicators at the sub-catchment scale are spatially weighted by sectoral water use to determine average exposure of each sector
within the given country or river basin. For a more complete explanation please see our
